Synthesis of uniform core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Synthesis of core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice. Abstract This study introduces a novel synthesis method for core‐shell calcium hydroxide‐calcium carbonate (CSCC) biocidal particles by inducing a phase change in liquid CO2$$ {\mathrm{CO}}_2 $$, thereby coating CaOH2$$ \mathrm{Ca}{\left ...

Revisiting acidulation for tall oil and lignin manufacturing

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Low‐Micromolar Quantification of Fluorinated Analytes Using Hyperpolarized 19F Benchtop Nuclear Magnetic Resonance

open access: yesChemistry–Methods, EarlyView.
Limits of detection and quantification of fluorinated analytes by 19F benchtop (1 T) NMR spectroscopy in the high nanomolar to low micromolar range are achieved using signal amplification by reversible exchange (SABRE) combined with the multiplet‐refocusing technique, SHARPER (Sensitive, Homogeneous, And Resolved PEaks in Real time).

Direct Quantification of Ammonia and Alkylamines in Aqueous Environments Using Solid‐Phase Microextraction‐Gas chromatography‐Mass spectrometry

open access: yesChemistry–Methods, EarlyView.
Fast and Facile! The use of a solid‐phase microextraction fiber allows direct sampling of aqueous solutions of ammonia for quantification using gas chromatography‐mass spectrometry (GC‐MS). The technique is insensitive to the presence of organic cosolvents or transition‐metal ions, making it particularly well suited for the analysis of catalytic ...

Classifying the Natural Tooth Color Spaces of Different Ethnic Groups

open access: yesColor Research &Application, EarlyView.
ABSTRACT This study aimed to classify the natural tooth color spaces of various ethnic groups and assess the coverage error (CE) of the Vita 3D‐Master shade guide. A sample of 490 volunteers from five ethnic backgrounds participated, with inclusion criteria set for adults aged 20– to 45 with healthy, correctly aligned natural teeth free of restorations.
